The clothing should be free of symbols of other religions (such as crosses etc.) and should not contain images of animate beings.

The clothing must not be one of fame and vanity.

It’s worth noting that Muslim men also have to cover their bodies, but to a lesser extent, since males are physically different to women, and the women is adornment! People generally love to admire female beauty, studies and research point to that fact, so its more apt that women cover their bodies to a greater extent.

The intention behind observing Hijab, is an obedience to the command of the Supreme Creator, The One True God, Allah. Muslim men and Muslim women observe the etiquette of Hijab in clothing and conduct, out of faith and God-Consciousness,

Allah says in the Qur’an:

‘Tell the believing men to reduce [some] of their vision and guard their private parts. That is purer for them. Indeed, Allah is Acquainted with what they do. {30}

And tell the believing women to reduce [some] of their vision and guard their private parts and not expose their adornment except that which [necessarily] appears thereof and to wrap [a portion of] their headcovers over their chests and not expose their adornment except to their husbands, their fathers, their husbands’ fathers, their sons, their husbands’ sons, their brothers, their brothers’ sons, their sisters’ sons, their women, that which their right hands possess, or those male attendants having no physical desire, or children who are not yet aware of the private aspects of women. And let them not stamp their feet to make known what they conceal of their adornment. And turn to Allah in repentance, all of you, O believers, that you might succeed. {31}

[Qur’an, 24:30-31]

And Allah says in the Qur’an:

“O Prophet, tell your wives and your daughters and the women of the believers to bring down over themselves [part] of their outer garments. That is more suitable that they will be known and not be abused. And ever is Allah Forgiving and Merciful.” [Qur’an 33:59]
